Deep and Vacuum Ultraviolet Spectrophotometer
Do you test transmittance and reflectance in the Vacuum Ultraviolet? Do you provide optics, coatings, photo resist materials, and substrates for the energetic ultraviolet? The VUVAS 1000 directly measures reflectance and transmittance properties of vacuum ultraviolet (VUV) optical components. The VUVAS 1000 system works from 120 to 350 nanometers with high throughput, strong signal levels and excellent reliability. The system uses a high throughput vacuum monochromator, focused light source, a sample chamber capable of holding multiple samples, detectors, and an oil free vacuum pumping (or purge) system.
The VUVAS 1000 operates by first scanning and storing the source's output. A second scan is made with the sample optical component in the light path. The ratio of the stored scan vs. measurement scan yields the optics reflectance or transmittance properties as Percent. The same detector is used for both scans so the results are Absolute. Accurate measurement of optical properties can be made over a wide angular. Polarizer’s have been developed and are available for the system too.
The VUVaS 1000 comes complete with vacuum pump and gauge, or purge-gas system. Easy to use Spectrometer Control Software (LabView™ based) controls automated parameters and signal recovery.
